I took a break from my increasingly frustrating level to make an Imperial AT-AT walker that finally actually works!

Level Name: AT-AT Walker
Creator: SalieriAAX

I had to make a major compromise with the legs, unfortunately. Wobble bolts are really awkward on walking things and they seem to hate moving in opposition to one another (ie, having the leg bend at the knee in the opposite direction to the bend at the 'hip'. So now the legs are entirely piston driven. It walks quite nicely all the same, it's just not as beautiful as the walking motion I had set up that ran smoothly in the air, attached to static material, but had the AT-AT doing backflips when I set it loose.

I've learned a few lessons while building this. The most useful one is that, when working with pistons, it's best to use the absolute minimum strength required for the job, as this stops the piston going haywire if something unexpected happens to it. This is especially improtant if you have more than one piston operating in the same system, as, if they get just a degree or two out of whack, high strength pistons will create a lot of tension in the system and send things flipping all over tha place. Unfortunately this doesn't help with wobble bolts - they're still a nightmare.

The AT-AT is still very much a work in progress. A couple of things I know I need to add are sound effects for everything but the blasters and quite a lote more sticker detail. Anything else I'm open to suggestions - It's pretty much full scale, which means it's a bit too big to use in any kind of level, but I have a couple of ideas to give driving it a bit of purpose.

Incidentally - does anyone know what colour the secondary blasters are supposed to be? I can't remember seeing them used in the movies. I've done them green anyway.

EDIT: Had to re-upload. I said 'cockpit' in one of my instructions magic mouths and it got x'ed out - naughty me! Also, the neck and cannon had started acting up, having never done so before, so those have been fixed too.

Oh what a clever Chappie you are salieri, hats off to you, and a bow!! LOVE it!!

I don't want to criticize this but I know how helpfully constructive criticisms are:

Make it smaller, if it was smaller you could see the whole thing in motion, to go to all that effort of making it and people not being able to see the whole thing is a terrible waste. (if i ask VERY nicely and add a few cherries, could you explain how you make it rock up and down so only two legs are in contact with the floor at once??) Is the main body suspended on a running piston?
Beautiful use of stickers NO NEED to add any more, perfect as itis my clever friend!
So happy when the door opened to allow you in the head, shooting the blasters would be BRILLIANT fun if there were something to shoot at (which I'm sure you'll add) Again, if it was smaller you'd have a better view (if only the cameras allowed you to zoom out further)

Interesting point about the strength settings on the pistons, Ive NEVER used it.I always assumed that if it was set low, then they wouldn't move large objects, what IS the point of the setting?

Game play 9 (Not a 10 'yet' as its not complete!
Graphics 10 (For what there is of it so far)
Fun factor 11 (sorry 10)

Thanks so much for your response. I totally get what you mean about the size. It would be much more usable if it were smaller. Then again the sense of scale is quite satisfying. I'll see what I can do.

I just typed out a really long explanation of how I do different styles of walking but I lost it by clicking the wrong button. I'll type it out again when I can muster the energy to go through it all again - but rest assured for now that there aren't any tricks or hidden pistons or trolleys - it actually walks on its own legs and isn't attached to anything. I like the challenge ^_^ .

Oh NOW i'm impressed!! No hidden running gear!!! No wonder you won't divulge your secrets! (or DID you, and then used a jedi mind trick on me?)

As for 'hitting the wrong key hahahahah...last night that very same thing happened to me...kinda. Just finshed writting up my level showcase thread for 'Pirates of the carob bean, and the computer shut it self down for updates (took me 35 mins to write, all lost) , sooooo...I did it all again, three quaters of the way through, hit the close button by mistake....lost again. I SO nearly punched this Feckin laptop...took me almost two hours in the end to post that thread lol!

Cant wait for another update of this At-AT!!!!

Well, I'd typed it all out in the quick reply, and then instead of clicking 'post quick reply' I hit 'reply to thread'. I've done that so many times now. Clicking back in my browser didn't bring it back either. I've done it dozens of times on this forum already.

Thanks again for the feedback! I will get around to playing your levels and reviewing them, by the way, they look amazing!

I have to say one amazing at-at I love how it worked just using pistons too and being able to go into the head I have to say I can not wait for this level to be done.

Thanks tominater! I've just been making an AT-ST and a TIE Fighter, both of which I'm really pleased with (if I could just get the **** jetpack in the TIE fighter to stop drifting between saves...) but I won't publish them until I have something to do with them, as I don't want this to turn into a "LOOK AT TEH VEHICES I CANS MADE" thread.

Generally, though, I spend so much time making walking machines and not making levels - would anyone be interested in a kind of 'How To' or step by step guide to making walkers? It could save other people a lot of experimentation if I explained everything I've worked out about snyching and timing in pistons and wobble bolts and things to make reliable walking mechanisms, but at the same time I don't want to just assume that anyone wants to know what I have to say about them.

Do it! When i think of someone who is a really experienced Vehicle Creator, its you. I think its like you say: you could save much time for some people! Besides that it seems like tutorials are well accepted by the community.

LOL, the people that matter are VERY interested, for those that are not, well, they don't have to read it (Not that there'll be many) The more in depth the bester I say. Pictures if you can, if not i'll take them for you.

Wandering jet packs: Surround them with a solid material (In 'Pirates of the carob bean' in the fuse room, note how i did it. I 'm not sure how thick the 'wall' has to be to stop it wandering, but it works a treat)

best of luck!

If anybody can do a "LOOK AT TEH VEHICES I CANS MADE" thread, it's you salieri. :) You have a real talent for this kind of thing.

The walker is amazing! Of course I love all the attention to detail and the faithfulness to the movie. For whatever reason my favorite bit about the whole thing is the way the head and blaster turrets move as you fire the weaponry. With the cannon, the head tilts down in just the right way, as though it's about to pick a snow speeder out of mid-air. Very, very cool. Your "constant speed" double-3-way-switch mechanism is a brilliant way to control any vehicle, especially something like this.

I can't wait to see what you do with this beast! Even a simple "Battle of Hoth" type of level would be great. It would be unbelievably fun if you got to be the Empire, blasting puny rebels to bits as you make your way to the shield generator. :)

5 stars and hearted!

Thanks a lot. I have to say working on it has got me quite enthused - full of ideas. My steampunk level can wait a bit until I can deal with the lag issues. If I do make a level with it I thought it would be quite good to add it in at the end, as a kind of climax, since it doesn't really make for a very exciting full level, just sitting in the cockpit (blush) with your finger on the 'r' button. For example, you're an imperial soldier that has overslept on the day of the Battle of Hoth, and have to make your way to the front line using several different vehicles, and jump into the AT-AT just in time to stomp on a few rebels and deliver the finishing blow to echo base.

I'm glad you liked the speed regulator. I'm writing a basic walking "How To" now, but after that I'm thinking of doing an advanced vehicle controls and logic guide - controlled acceleration, braking, etc. I'm sure some of the systems I've worked out won't be news to a lot of people, but they're not things I've read anywhere else and I'd really like to see people use fewer rocket-propelled cars. I think people assume that because of the very sudden torque you get, even using a speed-set three way switch, when using motor bolts, that it's impossible to have a really fast motor-bolt powered vehicle that doesn't do wheelies or flip over as soon as you touch the switch. You can get some really satisfying behaviours if you're prepared to get your hands dirty with some extra switches and pistons and winches.

Working on a little level to accompany the walking "How To" now with illustrations and ideas for how to implement the mechanics. Just made a stomping T-rex that I'm really pleased with, and it doesn't even do anything but walk along. I wish I could just make machines for other people's levels.

This is an impressive walking machine. Congratulations, you're really a master of this type of vehicles. Can't wait for the full level.

Hey salieri,

That was mind-boggling! I played this since you first posted it, but I never had the time to comment; I'm sorry for the delay. Since the very beginning, I was impressed at how well your creations function. I remember being particularly harsh on the aesthetics of your Airship, but that misrepresented how I truly felt about your talent. The movement of that airship was flawless, and you managed to out-do yourself with Colossal Calamity, which just totally blew me away in terms of your amazing stickerwork, and of course, greasy smooth mechanics.

Now this creation is a whole new level of wow. I can't even begin to wrap my little mind around the workings under the hood on this one, so again, I'll just comment on how impressed I was with the execution and good looks. To be honest, I was a little confused at first at exactly what the three-way switches did, so I just moved them a little here and there and proceeded to the "cockpit." I pressed "R" as commanded, and woah, I almost fell out of my chair! The recoil of the turet made me gasp with awe. I was still in a daze after beholding the sheer size of the vehicle, not to mention the rocket smoke smoldering underneath it, that this little movement just overwhelmed me.

So at this point, the AT-AT was still not moving so I returned to the three way switch to figure out what it actually did. Holy cow, it moves! And not just move, but Walk! Walking takes a whole lot of coordination, and you did wonders with that. And to think you did all of this with pistons? Wow!

I was also going to comment on your superb stickerwork again, but everything else has already impressed me beyond belief. Please, please work this into a level, even if it is only like Colossal Calamity...

Here's 5:star:s and a level heart for almost injuring me. ;) (I hearted you already!)

Bowing to the master,
jeffcu28

DON'T LOOK AT ME!

Sorry, I meant congrats on the Spotlight! :p


EDIT: Eh, on your other level. I meant. Okay, so I was tired. :blush:

You saw nothing. I was never here. ;)
